Feng Qiwu learned that Wen Chenyi had obtained the treasure map and asked the emperor to surround the academy on charges of treason.Wen Chenyi asked Cui Jun to take his family to escape, and he and Cheng Yiyi entered the cave to find the treasure.Among the treasures, they found ancient paintings, which were the medium for Cheng Yiyi to return.
